SIGIL

Firma

Firma is the chief setting of the campaign, an Earth-like planet abundant with life, magic, and civilization. Although SIGIL takes place on Firma, it is really set within the Known World of Firma, which covers only a portion of the planet's surface. A strange mystical phenomenon known as the Pale prevents travel into or out of the Known World.

Firma itself is slightly larger than Earth, though retains essentially the same gravity. It is part of a broader star system, and possesses three moons, Eris, Eros, and Yura.
